A shaft is loaded in bending and torsion such that M_a = 600 lb-in, T_a = 400 lb-in, M_m = 500 lb-in, and T_m = 300 lb-in. For the shaft, S_u = 100 ksi and S_y = 80 ksi, and a fully adjusted endurance limit of S_e = 30 ksi. At a notch, K_f = 2.2 and K_fs = 1.8. With a design factor of 2.0, determine the minimum acceptable diameter, using a. Gerber, b. Goodman,

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
